Abstract

Procedimento continuo per la fabbricazione di particelle solide di persali di un metallo alcalino rivestite mediante cristallizzazione di una soluzione acquosa sovrasatura di persali e rivestimento delle particelle di persali in un tino di post - cristallizzazione nel quale si introduce almeno un agente di rivestimento e si realizza una cristallizzazione dell'agente di rivestimento attorno alle particelle di persali in condizioni regolate di temperatura e di agitazione.Continuous process for the manufacture of solid particles of alkali metal persals coated by crystallization of a supersaturated aqueous solution of persals and coating of the persal particles in a post-crystallization vat in which at least one coating agent is introduced and a crystallization of the coating agent around the persal particles in controlled conditions of temperature and agitation.
